Ninjam - Skype for musicians

Justin Frankel (the creator of Winamp) has a new project called Ninjam. He announced it here today and it’s extremely cool.

Ninjam allows two or more people to jam through the net with real audio (no MIDI goofiness like past internet jamming software). It’s like Skype for musicians, though the music is delayed a few measures to keep everything in sync. You plug your instruments in, the software provides a beat. Then you find out what a crappy guitar player you are.
